Description: This video explains how to interpret the slope and y-intercept of the regression line and how to use the Line of Best Fit to make predictions.
UPDATE ERROR: at approximately 4:40 in the video, the teacher made a calculation error. The teacher accidentally hit the + button and instead of the x button. The calculator shows 20,681 + 1.8 - 17,481. This should actually be 20,681(1.8) - 17,481 = 19,744.80
